Configuration

Check whether the available current from the electronics cover power supply unit is sufficient for the total current demand of all consumers:

  1. Determine the available current from the electronics cover according to the following table:

Electronics cover

Available current
without external
24 V supply

Maximum current
with external
24 V supply

Size 1

Size 2 without fan

820 mA

1250 mA

Size 2 with fan

1180 mA

1600 mA

  1. Sum up the current demand of all consumers according to the following table:

Consumer

Current requirement

 

Electronics cover

(Basic requirement)

Size 1

Size 2 without fan

210 mA

Size 2 with fan

570 mA

1st

MOVILINK® DDI encoder (..Z)

120 mA

2nd

Keypad (CBG..)

50 mA

3rd

Safety technology

STO connected

0 mA

Internal STO jumpered

20 mA

4th

DC 24 V output

Max. 100 mA

  1. Compare the total current demand of all consumers to the available current without external 24 V supply (i.e. 24 V through internal power supply unit):

If the total current demand of all consumers is greater than the available current from the electronics cover power supply unit, you must supply the drive unit with 24 V externally.

In this case, the specified maximum currents must not be exceeded.
